Know More About OpenVTx

Big thanks to Jye Smith and all contributors for their time and energies to OpenVTx project.

OpenVTx refers to open source video transmitter firmware for the FPV community, which aims to provide firmware with both the SmartAudio and Tramp protocols. Either protocol can be used on the flight controller and on VTx power up the protocol used is automatically detected by OpenVTx. For more information, you can know it from OpenVTx GitHub.

Bullet Point

An open-source video transmitter with OpenVTx firmware. The A03 VTX supports SmartAudio and Tramp protocols. Through these protocols, the flight controller is able to adjust the video transmitter settings, which are the power, the band, and the channel of the transmission.

A03 VTX is a high-quality 5.8GHz VTX with strong anti-interference ability and stable transmission. Comes with PIT/RCE/25mW/100mW/400mW adjustable output power, allowing the perfect amount of output power to be selected based on your FPV needs.

Overall weighing 4.9g with a small-size layout, A03 VTX comes with a 26*26mm mounting hole and is perfectly suitable for whoop or toothpick drones like the X-Knight series, Beta85X/95X series, TWIG series, and Pavo series drones. 

Featuring a fixed mounting hole and 6-pin connector, less solder work needed, which makes it’s super easy to install.
